Thanx for the test!
Is it field curvature which has less impact on typical real life use or is the lower resolution at borders real?

Field curvature (as well as slight decentering) is compensated in the tests by refocusing at the specific test spot on the image field. In the real life you may see it at 16mm at large aperture settings when taking images of a flat object. However, it is not extreme.
